摘要

Jozef Stefan Institute (JSI) and Westinghouse have performed reactor physics analysis of the several NPP Krsko cycles using their respective core simulator packages, e.g. CORD-2 and NEXUS/ANC 9. This paper shows the performance of each core simulator to predict the plant physics behavior, specifically analyzing the comparison vs. measurements for the key core parameters. Critical boron concentrations, control rods worth and isothermal temperature coefficient are compared to the measured values. The results show satisfactory performance from both code systems and their adequacy to support the core design calculations and fuel loading optimization for the Krsko NPP.
